Angry Birds and More at Canstruction 2011 in NYC

The Canstruction 2011 exhibit is on at the World Financial Center in New York City -- and it's free to visit! In its 19th year and part of a public food drive for City Harvest, this annual event is a competition that helps to raise canned food for charity. In 2010, the event raised over 2 million pounds of food, says the Canstruction website.

For Canstruction 2011, which is on until Nov. 21, 100,000 cans of food have been put to use by local architecture and design firms, who have created 26 spectacular designs. Among them are replicas of a sinking Titantic ship, Alexander McQueen's staggering Lady Gaga shoes, Angry Birds, the Brooklyn Bridge and more.
